The prolific forward joins on a four-year deal, reported by Miles Chambers of Goal.com. BVB's announcement offers a boost of good news after the side's 3-2 Champions League elimination at the hands of Real Madrid, despite JurgenKlopp's team threatening a comeback with a 2-0 second-leg victory.

Ramos will head to the Westfalenstadion at the end of the season. A proven Bundesliga scorer, the Colombian international has continued to impress since his European arrival in 2009. He has notched 16 goals and provided five assists in 29 appearances during the domestic campaign, per WhoScored.com, scoring 43 percent of Hertha's goals along their run to 10th place.

Klopp will call upon the 28-year-old to help plug the chasm left by Robert Lewandowski. With the Polish star's summer move to Bayern Munich confirmed, Dortmund's cut-and-thrust attack faces a major reshuffle.

Lewadowski has one goal more than Ramos in one fewer appearance, indicating the versatile Colombian is capable of making an impact under Klopp's tutelage. Ramos netted the equaliser when Hertha beat Dortmund 2-1 in December and has also scored two goals in as many matches against Bayern Munich this season.

Ramos joins the signing of Ji Dong-Won, who agreed a summer move to Dortmund back in January, per BBC Sport. The duo will compete alongside Pierre-Emerick Aubameyang for a place in the starting lineup, as Klopp looks to stack his options ahead of Lewandowski's exit.

Radamel Falcao's recent injury means Ramos could play a key part in Colombia's World Cup campaign. Although the Monaco forward should be back in time for the Brazilian festivities, reported by L'Equipe (via Goal.com), his lack of game time may see Ramos called upon with greater intensity.

As such, Klopp's decision to tie the striker up before the tournament may be a wise one. Many players' prices are sure to increase if they perform well on the big stage, meaning Klopp has done well to bypass a potential bidding war with rival clubs.

Replacing Lewandowski's excellence is certainly going to be difficult. While Klopp is yet to land the headline-grabbing, world-renowned goalscorer BVB fans crave, Ramos is an astute signing ahead of a transitional period for the club.
